See the touchscreen of the future: your own skin

Experimental sensor turns an entire arm into a controller

There's only so much control a tiny touchscreen and dial can bring to a smartwatch, but what if you could control your wearable gadget using your whole arm as a trackpad?

This is the sorcery... I mean, concept behind SkinTrack, an experimental technology that allows a device, like a smartwatch.

Effectively, it would be able to read swipes, drags, presses, and even drawings made against your skin as if they were inputs on a touchscreen.

How it works

The core technology behind the skin-powered screen are pairs of electrodes that read a signal-emitting ring that essentially turns the user's forefinger into a stylus. The electrodes trace an X-and-Y-axis reading on your skin relative to where your finger is placed - even with clothing on - and translate the motions into commands.
